Hello,

im running the LWIP Stack on Freertos on a STM32. Evertyhing runs fine until
the optimization -o1

when turning on -o2 and higher some problems occur. At First a mailbox error
is detected with the message type "75" (0x4b) . After that only Arp packages
(0x608 , 1544) are incoming and detected, no ipv4 packets. 

So i cant use any ipv4 Features. Is this a known bug? 

Using Version 2.0.3 
/** X.x.x: Major version of the stack */
#define LWIP_VERSION_MAJOR      2
/** x.X.x: Minor version of the stack */
#define LWIP_VERSION_MINOR      0
/** x.x.X: Revision of the stack */
#define LWIP_VERSION_REVISION   3
